[0028] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0030] It should be noted that geothermal refers to the general term for the temperature of the soil at the surface and at different depths below the ground. The unit is degrees Celsius (℃); the interior of the earth is a huge heat reservoir. For example, the temperature of lava ejected from volcanoes is as high as 1200℃~1300℃, and the temperature of natural hot springs is mostly above 60℃, and some are even as high as 100℃~140℃. These heat from the interior of the earth can be converted into energy. When this heat seeps out of the surface, it becomes a geothermal resource. In densely populated areas with rich geothermal resources, geothermal heating is generally used for community heating. However, depending on the area of ​​the community, the temperature of geothermal heat after mining is not stable enough for heating use. It is often necessary to coordinate other energy sources to heat the circulating water heated by heat exchange with geothermal heat before heating for community users. However, the existing coordinated heating energy often uses traditional fossil fuels, which not only has high consumption and use costs, but also produces a large amount of pollution emissions, seriously affecting the environment. Therefore, how to reduce the cost of geothermal heating and reduce environmental pollution is a problem that needs to be solved urgently.

[0031] The main solution of the present application is to provide a heating system, which includes a main heating module and an auxiliary heating module. The main heating module is used to extract heat from the geothermal heat source and exchange the extracted heat energy with the initial circulating water to obtain geothermal hot water. The auxiliary heating module is used to heat the geothermal hot water to a preset demand temperature based on a preset renewable energy source to obtain target hot water if the temperature of the geothermal hot water is lower than the preset demand temperature.

[0032] The heating system provided by the present application exchanges the extracted geothermal heat energy with the initial circulating water to obtain geothermal hot water, and further heats the geothermal hot water with renewable energy to obtain target hot water. Compared with the prior art that uses traditional fossil fuels to heat geothermal hot water, the cost of geothermal heating is reduced and environmental pollution is reduced.

[0033] Based on this, the first embodiment of the heating system of this application is proposed, please refer to Figure 1 , Figure 1 This is a structural block diagram of the first embodiment of the heating system of the present application.

[0034] In this embodiment, the heating system includes:

[0035] The main heating module 11 is used to extract heat from the geothermal heat source and exchange the extracted heat energy with the initial circulating water to obtain geothermal hot water;

[0036] It should be noted that the geothermal heating system refers to a heating system that uses geothermal energy as the main heat source. Geothermal heating systems can be divided into direct heating and indirect heating according to the way the geothermal flow enters the heating system. Direct heating means directly introducing the geothermal flow into the heating system, and indirect heating means that the geothermal flow transfers heat energy to the circulating water of the heating system through a heat exchanger, and the geothermal flow does not directly enter the heating system. In the heating system provided in the present application, an indirect heating method is adopted, that is, the geothermal flow transfers heat energy to the circulating water of the heating system through a heat exchanger.

[0037] Specifically, the main heating module 11 first extracts heat from the geothermal heat source. Geothermal heat can exist in the form of groundwater, rock or geothermal well, and the heating system extracts the heat energy of the geothermal heat source through a heat exchange device. The extracted geothermal heat energy is heat exchanged with the initial circulating water, and the heat energy of the geothermal heat source is transferred to the initial circulating water to increase its temperature. After the heat exchange, the initial circulating water becomes geothermal hot water, and its temperature is higher than before.

[0038] The above steps ensure that the geothermal thermal energy is effectively utilized and converted into hot water that can be used for heating.

[0039] It should be noted that the initial circulating water refers to the water used as a heat exchange medium at the beginning of the operation of the heating system. It does not come into contact with geothermal or other heat sources at first, but serves as the initial medium in the circulation system. In a geothermal heating system, the initial circulating water is usually filled into the system for the first time after the system is built, and is used for heat exchange with the geothermal heat source in the main heating module. The initial circulating water usually circulates in the system, exchanges heat with the geothermal heat source through a heat exchange device, transfers geothermal energy to water, forms hot water, and is then used for heating or hot water needs. Geothermal heat source refers to the heat energy resources inside the earth, usually from the heat inside the earth. This heat source can exist in the form of underground rock layers, geothermal water veins, or geothermal wells. Geothermal heat is the heat energy inside the earth, usually converted from magma activity and geothermal energy inside the earth. Geothermal heat source is a renewable energy source because the heat inside the earth is continuously generated. Using geothermal heat source for heating is an environmentally friendly and sustainable way because it produces almost no greenhouse gases such as carbon dioxide, and does not pollute the environment like traditional energy sources such as coal or gas.

[0040] The auxiliary heating module 12 is used to heat the geothermal hot water to the preset required temperature based on the preset renewable energy to obtain the target hot water if the temperature of the geothermal hot water is lower than the preset required temperature.

[0041] Specifically, the auxiliary heating module 12 first monitors the temperature of the geothermal hot water. If the temperature of the geothermal hot water is lower than the preset required temperature, the auxiliary heating module 12 determines the amount of heating required and calculates the required heating energy, and then selects a suitable energy source based on the preset renewable energy (such as solar energy, wind energy, biomass energy, etc.) for heating the geothermal hot water.

[0042] Furthermore, the selected renewable energy is converted into thermal energy through a corresponding heating device or system to heat the geothermal hot water. After heating, the temperature of the geothermal hot water reaches or exceeds the preset required temperature, thereby obtaining the target hot water, which can continue to be used for heating or hot water needs of the heating system.

[0043] Through the operation of the auxiliary heating module 12, even if the temperature of the geothermal hot water is lower than the preset required temperature, it can be heated by utilizing renewable energy, thereby ensuring that the heating system can always provide hot water that meets the demand.

[0044] It should be noted that the preset demand temperature refers to the temperature standard that the heating system needs to reach, which is determined during the design or planning stage. This temperature is usually set according to the usage scenario and demand. The target hot water refers to the temperature of the water finally obtained by the heating system after the heating process. In the case of the auxiliary heating module 12, if the temperature of the geothermal hot water is lower than the preset demand temperature, the temperature of the water finally obtained after the heating process is the target hot water. The temperature of the target hot water should reach or exceed the preset demand temperature to meet the actual needs of the heating system.

[0045] The heating system provided in this embodiment includes a main heating module 11 and an auxiliary heating module 12. The main heating module 11 is used to extract heat from the geothermal heat source and perform heat exchange between the extracted heat energy and the initial circulating water to obtain geothermal hot water. The auxiliary heating module 12 is used to heat the geothermal hot water to the preset required temperature based on the preset renewable energy if the temperature of the geothermal hot water is lower than the preset required temperature to obtain the target hot water. In this embodiment, the heating system performs heat exchange between the extracted geothermal heat energy and the initial circulating water to obtain geothermal hot water, and further heats the geothermal hot water with renewable energy to obtain the target hot water. Compared with the prior art that uses traditional fossil fuels to heat geothermal hot water, the cost of geothermal heating is reduced and environmental pollution is reduced.

[0046] Based on the above first embodiment, a second embodiment of the heating system of the present application is proposed. Figure 2 , Figure 2 This is a structural block diagram of the second embodiment of the heating system of the present application.

[0047] like Figure 2 As shown, in this embodiment, the heating system further includes a supply module 13, and the supply module 13 is used to supply the target hot water based on a preset optimal heating state.

[0048] It should be noted that the preset optimal heating state is the best operating state of the heating system determined in the design or planning stage, which can be set in advance based on specific energy utilization efficiency, hot water temperature, system stability and other factors.

[0049] Specifically, the supply module 13 provides the target hot water to the end users of the system according to the preset optimal heating state. The supply module 13 first monitors the target hot water obtained after heating by the auxiliary heating module 12 to ensure that its temperature meets the requirements of the preset optimal heating state. Once the target hot water reaches the requirements of the preset optimal heating state, the supply module 13 will deliver it to the end users or equipment of the system for heating, hot water and other needs.

[0050] Optionally, the supply module 13 will continuously monitor the system operation status and the actual needs of the end users, and adjust the supply of hot water according to the real-time situation to ensure that the system operates in the optimal state and meets the needs of the end users.

[0051] Through the operation of the supply module 13, the heating system can effectively manage and distribute the target hot water, and monitor and adjust the overall operating status of the system in real time, thereby ensuring that the system can always operate in the best heating state.

[0052] Based on the above first embodiment, in this embodiment, the heating system further includes an equipment maintenance module 14, and the equipment maintenance module 14 is used to monitor the initial circulating water, the heating pipe, the heat pump and the heat exchanger, and issue a heating fault message when an abnormality is detected.

[0053] Specifically, the equipment maintenance module 14 regularly monitors parameters such as the water quality and flow rate of the initial circulating water to ensure that it is in good condition, does not contain impurities or pollutants, and maintains normal fluidity. Regular inspections are carried out on the heating pipeline, including checking whether the pipeline has leakage, corrosion, blockage and other problems, to ensure the integrity and smoothness of the pipeline, and to avoid heating interruptions or failures due to pipeline problems. Regular inspections and maintenance of heat pumps include checking the operating status, pressure, temperature and other parameters of the heat pump to ensure the normal operation of the heat pump, and to promptly identify and deal with possible problems. Regular inspections of heat exchangers include checking whether the surface of the heat exchanger is scaled, whether the pipeline is blocked, etc., to ensure the normal operation of the heat exchanger and the efficiency of heat exchange.

[0054] Furthermore, the equipment maintenance module 14 monitors the equipment operation status in real time through sensors and monitoring devices. Once an abnormal situation is found, such as abnormal water quality, pipe leakage, heat pump failure, etc., it immediately issues a heating failure message to remind relevant personnel to take timely measures for maintenance and processing to avoid damage or interruption of the heating system.

[0055] Based on the above first embodiment, in this embodiment, the heating system further includes a temperature monitoring module 15, and the temperature monitoring module 15 is used to monitor the temperature of the geothermal hot water. If the temperature of the geothermal hot water is not lower than the preset required temperature, the geothermal hot water is used as the target hot water.

[0056] Specifically, the main function of the temperature monitoring module 15 is to monitor the temperature of the geothermal hot water in real time, and to determine whether the hot water meets the requirements according to the preset demand temperature setting. The temperature monitoring module 15 monitors the temperature of the geothermal hot water in real time through sensors or other monitoring devices, and compares the monitored temperature of the geothermal hot water with the preset demand temperature. If the temperature of the geothermal hot water is not lower than the preset demand temperature, the system will directly regard the geothermal hot water as the target hot water without additional heating treatment. If the temperature of the geothermal hot water reaches or exceeds the preset demand temperature, the system will directly distribute the geothermal hot water to the end users or equipment of the system for heating, hot water and other needs.

[0057] Through the operation of the temperature monitoring module 15, it can be discovered in time whether the temperature of the geothermal hot water meets the standard, thereby reducing unnecessary energy consumption and equipment operation, and improving the energy utilization efficiency and operation efficiency of the heating system.

[0058] The heating system provided in this embodiment includes a main heating module 11 and an auxiliary heating module 12. The main heating module 11 is used to extract heat from the geothermal heat source and perform heat exchange between the extracted heat energy and the initial circulating water to obtain geothermal hot water. The auxiliary heating module 12 is used to heat the geothermal hot water to the preset required temperature based on the preset renewable energy if the temperature of the geothermal hot water is lower than the preset required temperature to obtain the target hot water. In this embodiment, the heating system performs heat exchange between the extracted geothermal heat energy and the initial circulating water to obtain geothermal hot water, and further heats the geothermal hot water with renewable energy to obtain the target hot water. Compared with the prior art that uses traditional fossil fuels to heat geothermal hot water, the cost of geothermal heating is reduced and environmental pollution is reduced.

[0059] Based on the above second embodiment, a third embodiment of the heating system of the present application is proposed. Figure 3 , Figure 3 This is a structural block diagram of the supply module in the third embodiment of the heating system of the present application.

[0060] In this embodiment, the supply module 13 includes a data collection unit 131 and a data analysis unit 132. The data collection unit 131 is used to obtain the temperature, flow, pressure and actual heating temperature in the heating pipe. The data analysis unit 132 is used to determine whether the current heating state is the preset optimal heating state based on the temperature, flow, pressure and actual heating temperature in the heating pipe. If not, adjust the preset heating parameters to adjust the current heating state to the preset optimal heating state, and supply the target hot water based on the preset optimal heating state.

[0061] Specifically, the data collection unit 131 is responsible for obtaining data such as temperature, flow, pressure and actual heating temperature in the heating pipeline in real time. These data reflect the key parameters of the operating state of the heating system and are an important basis for judging the performance and operating state of the heating system. The data analysis unit 132 analyzes and processes the data obtained by the data collection unit 131 to determine whether the current heating state is the preset optimal heating state. Analyze the collected temperature, flow, pressure and other data to understand the current operating state of the system. Compare the actual data with the preset optimal heating state to determine whether the optimal state is currently reached. If the current heating state does not meet the preset optimal state, the data analysis unit 132 will adjust the preset heating parameters according to the actual situation to optimize the operating state of the system. Based on the adjusted preset optimal heating state, the determined target hot water is allocated to the terminal users or equipment of the system.

[0062] It should be noted that the preset heating parameters are a set of set values ​​determined during the design or planning stage of the heating system, which are used to guide the operation of the heating system. These parameters include the temperature setting, flow setting, pressure setting, etc. of the hot water supply, which are determined based on comprehensive consideration of factors such as the system design requirements, usage scenarios, and user needs. The preset optimal heating state is the optimal operating state of the system determined based on a comprehensive consideration of the preset heating parameters and actual operating conditions. It is to achieve a balanced state in multiple aspects such as the highest energy utilization efficiency, stable system operation, and optimal end-user comfort by optimizing heating parameters and adjusting system operation modes on the premise of meeting user needs.

[0063] Through the operation of the data collection unit 131 and the data analysis unit 132, the supply module 13 can timely understand the operating status of the heating system, adjust and optimize according to actual conditions, ensure that the system always operates in the best heating state, and improve energy utilization efficiency and heating effect.

[0064] See also Figure 4 , Figure 4 This is a structural block diagram of the main heating module in the third embodiment of the heating system of the present application. Based on the above second embodiment, in this embodiment, the main heating module 11 includes a heat extraction unit 111 and a heat exchange unit 112. The heat extraction unit 111 is used to extract heat from the geothermal heat source through a heat pump to obtain geothermal heat; the heat exchange unit 112 is used to exchange the geothermal heat with the initial circulating water through a heat exchanger to obtain the geothermal hot water.

[0065] The heat extraction unit 111 extracts heat from the geothermal heat source through a heat pump. As a heat energy conversion device, the heat pump absorbs heat from the geothermal heat source, and then transfers the heat in the geothermal heat source to another medium through processes such as compression, transfer and release. Therefore, the heat extraction unit 111 uses a heat pump to extract heat from the geothermal heat source for subsequent heating use. The heat exchange unit 112 exchanges the extracted geothermal heat with the initial circulating water through a heat exchanger, and finally obtains geothermal hot water. The heat exchanger is a device that can realize heat transfer, which allows the geothermal heat to exchange heat with the initial circulating water, so that the temperature of the initial circulating water is increased, and finally the geothermal hot water for heating is obtained. The heat extraction unit 111 and the heat exchange unit 112 together constitute the main heating module 11, which realizes the heat energy extraction and conversion of the geothermal heat source, and provides the heating system with a basic energy source of geothermal hot water.

[0066] See also Figure 5 , Figure 5 This is a structural block diagram of the auxiliary heating module in the third embodiment of the heating system of the present application. Based on the above-mentioned second embodiment, in this embodiment, the preset renewable energy includes a first renewable energy and a second renewable energy, and the auxiliary heating module 12 includes a heat determination unit 121 and a heating unit 122. The heat determination unit 121 is used to determine the heating demand heat according to the temperature of the geothermal hot water if the temperature of the geothermal hot water is lower than the preset demand temperature; the heating unit 122 is used to determine the distribution ratio of the first renewable energy and the distribution ratio of the second renewable energy according to the heating demand heat, and based on the first renewable energy, the second renewable energy, the distribution ratio of the first renewable energy and the distribution ratio of the second renewable energy, heat the geothermal hot water to the preset demand temperature to obtain the target hot water.

[0067] Specifically, when the temperature of the geothermal hot water is lower than the preset required temperature, the heat determination unit 121 calculates the temperature difference between the current geothermal hot water and the preset required temperature, i.e., the heating required heat. The temperature of the geothermal hot water is monitored in real time by a sensor or a monitoring device, and the data is transmitted to the heat determination unit 121.

[0068] Further, after receiving the heating demand heat provided by the heat determination unit 121, the heating unit 122 determines the distribution ratio of the two renewable energy sources according to the preset first and second renewable energy sources and their performance characteristics. Based on the distribution ratio, the heating unit 122 adjusts the supply of the first and second renewable energy sources to meet the heating demand heat. The first renewable energy source may include solar energy, wind energy, etc., and the second renewable energy source may include biomass energy, etc. The heating unit 122 dynamically adjusts the distribution ratio of the two according to the current environmental conditions and the supply of renewable energy. The heating unit 122 supplies the adjusted first and second renewable energy sources to the heating equipment to provide additional heat. This heat is transmitted to the geothermal hot water through equipment such as a heat exchanger to increase its temperature until it reaches or exceeds the preset required temperature. The heating unit 122 monitors the temperature of the geothermal hot water in real time and ensures the stability and efficiency of the heating process.

[0069] Through the coordinated work of the heat determination unit 121 and the heating unit 122, the auxiliary heating module 12 can dynamically adjust the energy utilization ratio according to the actual heating demand and the supply of renewable energy, realize the intelligent heating of geothermal hot water, and thus ensure that the heating system can always operate in the best heating state.

[0070] Based on the above-mentioned second embodiment, in this embodiment, the first renewable energy is solar energy and / or wind energy, the second renewable energy is biomass energy, and the heating unit 122 is also used to obtain weather data, determine the distribution ratio of the solar energy and / or wind energy according to the weather data, determine the distribution ratio of the biomass energy according to the distribution ratio of the solar energy and / or wind energy, and based on the solar energy and / or wind energy, the distribution ratio of the solar energy and / or wind energy, the biomass energy, and the distribution ratio of the biomass energy, the geothermal hot water is heated to the preset demand temperature to obtain the target hot water.

[0071] Specifically, the heating unit 122 uses meteorological sensors or weather data sources to obtain real-time weather data, including information such as sunlight intensity and wind speed. These weather data reflect the availability of solar energy and wind energy, and can guide the heating unit 122 to adjust the allocation ratio of these renewable energy sources. The heating unit 122 determines the current solar energy and / or wind energy resource situation based on the acquired weather data. If the sun is sufficient or the wind is strong, the heating unit 122 will increase the allocation ratio of solar energy and / or wind energy accordingly to improve the utilization rate of renewable energy. According to the allocation ratio of solar energy and / or wind energy, the heating unit 122 determines the allocation ratio of biomass energy. As the second renewable energy source, when solar energy and / or wind energy resources are insufficient, the heating unit 122 will increase the allocation ratio of biomass energy to make up for the energy gap and ensure that geothermal hot water can reach the preset demand temperature.

[0072] Furthermore, the heating unit 122 adjusts the supply of solar energy and / or wind energy and biomass energy according to the determined distribution ratio of these energies to heat the geothermal hot water. The geothermal hot water exchanges heat with the renewable energy through a heat exchanger and other equipment, and finally reaches the preset required temperature to obtain the target hot water.

[0073] By acquiring and analyzing weather data in real time and adjusting the distribution ratio of solar energy, wind energy and biomass energy according to their availability, the heating unit 122 can flexibly optimize energy utilization and ensure that geothermal hot water can reach the preset required temperature under different environmental conditions.

[0074] Based on the above-mentioned second embodiment, in this embodiment, the heat determination unit 121 is also used to obtain the temperature of the geothermal hot water, and determine the geothermal heat according to the temperature of the geothermal hot water and the temperature of the initial circulating water, and determine the heating demand heat according to the geothermal heat and the preset total demand heat.

[0075] Specifically, the heat determination unit 121 obtains the temperature data of geothermal hot water in real time through a sensor or a monitoring device. The geothermal heat is calculated based on the difference between the temperature of the geothermal hot water and the temperature of the initial circulating water. The temperature of the geothermal hot water is higher than that of the initial circulating water, so the heat determination unit 121 converts this temperature difference into corresponding heat. The heat determination unit 121 compares the calculated geothermal heat with the preset total required heat to obtain the heating required heat. The preset total required heat is determined in advance based on factors such as system design and user needs, and is the total heat demand that the heating system needs to meet.

[0076] Through the above steps, the heat determination unit 121 can accurately calculate the heat of geothermal hot water and the current heating demand of the system. This process provides important reference information for the heating unit 122 to help it determine the appropriate renewable energy allocation ratio to meet the actual heating demand of the system.

[0077] In one embodiment, during the operation of the heating system, geothermal heat is extracted to the ground by a heat pump, and then the heat is exchanged with water by a heat exchanger to heat the water. At the same time, the temperature of the hot water is monitored in real time to determine whether it is necessary to cooperate with the auxiliary heat source for heating in the future. When the temperature of the circulating hot water is low and cannot meet the heating demand, other multiple energy sources are used to provide additional heat to the hot water after heat exchange with the geothermal heat source to heat it, and the overall heating temperature is assisted to rise to an applicable temperature so that it can be used to heat community users. During the heating process, the temperature, flow rate and pressure data in the heating pipeline and the weather and temperature data outside are collected. Finally, the collected temperature, flow rate and pressure data are combined with the actual temperature of the hot water to analyze whether it is in the best heating state. During the heating process, through real-time monitoring and intelligent regulation of the entire heating system, the supply ratio of each energy source can be dynamically adjusted according to the actual heating demand and energy supply situation, so as to achieve the optimal heating effect. The heating strategy can be dynamically adjusted according to the actual heating demand and energy supply situation to achieve precise heating while reducing energy consumption and carbon emissions.

[0078] The heating system provided in this embodiment includes a main heating module 11 and an auxiliary heating module 12. The main heating module 11 is used to extract heat from the geothermal heat source and perform heat exchange between the extracted heat energy and the initial circulating water to obtain geothermal hot water. The auxiliary heating module 12 is used to heat the geothermal hot water to the preset required temperature based on the preset renewable energy if the temperature of the geothermal hot water is lower than the preset required temperature to obtain the target hot water. In this embodiment, the heating system performs heat exchange between the extracted geothermal heat energy and the initial circulating water to obtain geothermal hot water, and further heats the geothermal hot water with renewable energy to obtain the target hot water. Compared with the prior art that uses traditional fossil fuels to heat geothermal hot water, the cost of geothermal heating is reduced and environmental pollution is reduced.
